Our one-piece, 70mm (70G-450) continuous thread (CT) gold/white metal plastisol lined caps are compatible with glass containers like Mason, Ball Kerr, Golden Harvest, and others.
They have are a regular mouth canning lid that fits in 70g-450 neck. Regular mouth jars are the most commonly-sized canning jar for honey and other foods and are suitable for most canning purposes.
When the gold metal plastisol lined caps are placed on a compatible 70 mm container, heating methods will heat the plastisol liner, causing it to solidify, creating a seal between itself and the container.
Button lids have a metal button on the top that is pulled during the heated canning process. No-button canning lids do not have a button and are typically used when not heated during bottling. Both lids will create an airtight seal because of the plastisol liner.
In addition to our regular mouth jars, these canning jar lids will also fit other canning jar brands such as Ball, Golden Harvest, Kerr, Atlas, and others.
